Leona recently announced that she was pledging to save Hopefield Animal Sanctuary in Brentwood, Essex - a charity that, as a passionate animal welfare campaigner and vegetarian, is very close to her heart. She has made several visits to the sanctuary in the past few months, most recently for a sponsored walk that raised over £14,000.

This event in LA kicks off a string of fundraising events that Leona will be involved in for the charity between now and Christmas. On Saturday Leona will host an evening of live entertainment (she will perform, as will friend Natasha Bedingfield) alongside cocktails and canapes.
